AIR-COOLING INTEBNAII-CODUSTIOH ENGINE.

Application mea ummber 11, 1922. Serial 110. 000300.

This invention pertains to the cooling of internal combustion engines and more specifically to means for directing a cooling fluid over an internal combustion engine of the single-row-in-a-line type for airplanes or mechanical transport vehicles.

It is an object of the invention to simplify the cooling of engines of the type referred to and to insure the efficient working of such means. v

It is afurther object of the invention to. .sensibly and uniformly distribute the air supply to all the cylinders.

It is a further object to rangement whereby the engine housing Wlll be substantially divided along -a medial line to facilitate and direct the cooling of the engine and whereby the hood of the engine may be lifted or removed from either side present day providing a clear view of the engine without the necessity of removing further obstructions.

Other objects will appear infra, as the de-- scription of a specific embodiment of the invention proceeds and as claimed.

In the drawing:

Fig. I is a side elevation of an engine and tion and to divide the engine space in two. 'Toone;

end of this bafiie 2, is connected a deflecting 40 plate or battle 4 whereby air-drawn in to the engine space through a dummyradiator or other opening 6 by in 8, is forced to fpi'ass down on one side of the cylinders 10 o or er to prevent the momentum of the provide an ar-' as is usual with automobile engines of thehood partly in section, showing'the inven- Fig. II is a top plan viewof the engine the." en 'ne and forced out on the other side. In

drawn in carrying it (the air) past the first cylinders, a curved deflecting plate 12 is attached to one side of the engine hood 14.

This plate 12 forces the air between the fins of the front cylinders of the motor, thus insuring equal distribution of the cooling" medium.

The structure is so designed that air will be forced across the engine in the manner noted from Fig. I that I provide hinges 16 shown in the arrows in Fig. II. It will be for the usual hood covers andthe covers and hinge mechanism may be desi ed to be removed, as is now common in t e art, either together oralone with the baflle mechanism 2 etc., as desired, but I do not limit" myself to any specific manner of removal operation.

What I claim is:

1. In a cooling system for internal combustion engines having'a plurality of cylinders,a hood surrounding said en 'ne, means at the forward end of said hoo ing a flow of cooling mediu into said hood baflie means'on one side of said hood-adapted to guide said cooling'medium tothe opposite side of said hood, and a substantially arcuate said second named side of said hood for guiding the flow of cooling medium tangentially past said cylinders.

for inducshaped bafile plate positioned laterally of cooling medium tangentlally past said cylinders.

In testimony whereof I 11651: my signature.
